Hi again!
Can somebody explain (step by step) how can i build polyglots books?
Thanks in advance

Usage: "polyglot make-book <<options>".

"make-book" options are:

- "-pgn"

Name of the input PGN file. PolyGlot should support any
standard-conforming file. Let me know if you encounter a problem.

- "-bin"

Name of the output binary file. I suggest ".bin" as the extension but
in fact PolyGlot does not care.

- "-max-ply" (default: infinite)

How many plies (half moves) to read for each game. E.g. if set to
"20", only the first 10 full moves of each game will be scanned.

- "-min-game" (default: 3)

How many times must a move be played to be kept in the book. In other
words, moves that were played too rarely will be left out. If you
scan full games "2" seems a minimum, but if you selected lines
manually "1" will make sense.

Example: "polyglot make-book -pgn games.pgn -bin book.bin -max-ply 30".

Building a book is usually very fast (a few minutes at most). Note
however that a lot of memory may be required. To reduce memory usage,
select a ply limit.

Thanks, Bryan, i will try.
By the way, are in your plans to compile a very fast Phalanx-Reborn?
Ive saw that Jim found some errors in ponder..
